Studies in Sulphonamides : Part II. Preparation of NI-Hetero-Cyclic Substituted Sulphonamides from Alpha-naphthylamine and Evaluation of their Antibacterial Properties

A series of N^I-heterocyclic substituted naphthalene sulphonamides have been prepared in which the hydrogen atom of the sulphonamido group has been substituted by different nuclei, viz., thiazole, benzo­thiazole, pyridine and carbazole rings. All the seventeen compounds so prepared were screened for their antibacterial properties and some of these were found to be active 'in vitro' against S. aureus and E. coli.
